Prior to installation, sprinklers should be maintained in the original cartons and packaging until used to minimize the
potential for damage to sprinklers that would cause improper operation or non-operation.
The Protective Cap must remain on the sprinkler during installation and until the ceiling installation is completed. The
Protective Cap must be removed to place the sprinkler in service.
Use a torque of 7 to 14 ft.lbs (9.5 to 19.0Nm) to achieve a 1/2 inch NPT sprinkler joint. A maximum of 21 ft.lbs. (28.5 Nm) of
torque is to be used to install sprinklers. If you exceed the recommended maximum torque, this could result in damage
to the sprinkler inlet, which may lead to leakage from the sprinkler.
In case of insufficient adjustment in Cover Plate installation, do not try to overly tighten, screw the sprinkler too loosely
or make any modification to the cover plate assembly. Readjust the sprinkler fitting for a better fit.
Installing Procedure
Step 1
The installation requirements for the sprinkler are as follows: to be installed only in the pendent position with the waterway
perpendicular to the ceiling. Install the sprinkler fitting so that the distance from the face of the fitting to the mounting surface will
be nominally 1- 7/8 inch (47.6 mm) as shown in Figure 3.
Step 2
With pipe thread sealant applied to the threads, hand tighten the sprinkler into the sprinkler fitting. Then tighten it with the
Sprinkler Socket or Wrench & Socket Combination (Ref. Figure 4). The grooves of the Socket must fit perfectly with the grooves
on the Sprinkler for proper installation (Ref. Figure 4).
Step 3
If desired the Protective Cap may also be used to locate the center of the clearance hole by gently pushing the ceiling material
against the center point of the Protective Cap. Before the installation of the ceiling, the sprinkler installation can be started with
the 2 inch (50 mm) diameter clearance hole (Ref. Figure 3). Use the “Tolerance Limit of Ceiling Level” indicator on the
Protective Cap to check for proper installation height (Ref. Figure 3).

Step 4
Use the Protective Cap Removal Tool to remove the Protective Cap (Ref. Figure 5) and then push/screw a Cover Plate
Assembly on the Frame of the Sprinkler by hand until its flange just comes in contact with the ceiling (Ref. Figure 6 and Figure
7). Stop tightening the Cover Plate Assembly once the flange has come in contact with the ceiling. If the ceiling has been lifted
from its normal position in the process of tightening of the Cover Plate Assembly, readjust the cover plate assembly as
necessary. If the flange of the Cover Plate Assembly cannot come in contact with the ceiling sufficiently, readjust the sprinkler
fitting as necessary. When properly installed, there is a nominal 1/8 inch (3.2mm) air gap between the lip of the Cover Plate and
the ceiling, as shown in Figure 6
